Oxygen and Oxide Ion Concepts

The video tutorial explains how to draw the Lewis structure for both neutral oxygen and the oxide ion. It begins by detailing the process for oxygen, highlighting its six valence electrons. The tutorial then moves on to the oxide ion, explaining the addition of two extra electrons due to its negative charge. Finally, it covers the correct notation for the oxide ion, including the use of brackets.

What is the first step in drawing the Lewis structure for the oxide ion?

• Add extra electrons to the oxygen atom.

• Determine the charge of the oxide ion.

• Place brackets around the oxygen atom.

• Draw the structure for a neutral oxygen atom.

In which group of the periodic table is oxygen found?

• Group 15 or 5A

• Group 17 or 7A

• Group 14 or 4A

• Group 16 or 6A

How many valence electrons does a neutral oxygen atom have?

• Four

• Two

• Six

• Eight

What does the two minus charge in the oxide ion indicate?

• Two missing electrons

• Two extra electrons

• Two extra neutrons

• Two extra protons

How many total valence electrons are present in the oxide ion?

• Seven

• Six

• Nine

• Eight

What is the purpose of adding brackets around the oxide ion in its Lewis structure?

• To indicate the number of valence electrons

• To show the ion's charge

• To highlight the oxygen atom

• To separate it from other ions
